I have written about this in a previous post, but I think Terminal 3's parking garage deserves an official Bad Design Moment post. This is largely due to my sadness regarding the design reoccurring on a recent, unexpected, trip there. McCarran Airport's new terminal 3 is efficient, but the overall design is mediocre, certainly compared to the original terminal 1 building. The worst part of the new terminal building is the location of the parking garage's spiral ramp that is unsymmetrical within itself as well as missing a perfect opportunity to align with Maryland Parkway. It would have been an easy gesture to simply move the spiral, or the whole structure, to make the spiral align with Maryland Parkway or at the very least center it between the two stair towers. The parking garage s is a real beast and sad considering Vegas has some really well designed parking garages (including the one very near at terminal 1).
Below is a simple diagram illustrating the parking garage's many centers.
